Following the recent introduction (in April) of Vertex 4 SSDs based on the new Indilinx Everest 2 controller, OCZ has now rolled out the fourth generation of its mid-range Agility solid state drives.

Based on the same Indilinx Everest 2 controller paired up with 2Xnm synchronous MLC NAND chips, up to 1GB of DRAM cache, the new Agility 4 will be available in 64, 128, 256 and 512GB capacities and offer sequential read and write speeds of up to 400MB/s and 400MB/s. The write speed drops with capacity so the 128GB will max out at 300MB/s while the 64GB one drops down to 300/200 MB/s for read and write.

The random 4k read and write IOPS is set at up to 48k and 85k for the 256 and 512GB models. The 128GB one will max out at 58k and 72k while the 64GB one drops down to 46k and 47k IOPS.

Since it is based on the new Indilinx Everest 2 controller, the new Agility 4 SSD lineup features ECC correction, 256-bit AES-compliant data encription, SATA 6Gbps interface, TRIM and Indilinx nDurance 2.0 technology.

The entire series is backed by a 3-year warranty amd have already hit retail/e-tail in Europe with a price tag set at €74 for the 64GB, €120 for 128GB, €225 for the 256GB version and €490 for the 512GB version.
